Screw or auger flights are typically used to efficiently transfer fluid, granular or semi-solid materials in the mass-processing industry. By rotation of the flight, the material is carried along the surface of the helical coil section.

The means and method of manufacturing a conventional section screw flight involves compressing each section of the flight between sets of die having the appropriate shape. Each flight section is then typically welded to the shaft in turn to form a single finished conveyor screw.

Conventional die compression methods have several inherent disadvantages. This disadvantage involves that the shape of the ring is often required to repeat the die compression operation several times in order to match the shape of the die with the shape of the die on which the blank is compressed between, depending on the thickness of the blank material used. The requirement to repeat the compression cycle necessarily increases the production cost of the screw flight produced by this method.

In addition, the blanks typically undergo plastic deformation during the compression process, leading to inaccuracies in the flight profile beyond the desired manufacturing tolerances. Such deviations from the desired manufacturing tolerances necessarily lead to low quality products, which in turn lead to reduced product performance and life span.
